I own a couple of TomTom One GPS units, and I'd like to use one on my S40;  albeit with the last possible cosmetic impact on the bike.

The first thing I need is a 12 volt "cigarette lighter" receptacle on or near the bars.   Any recommendations  for something that will mount to the handlebars or to my mini-Switchblade Deflector windsheild?

Additionally, am I a total moron for thinking I could simply use the TomTom's suction cup mount to affix it to the Switchblade without it falling off mid-ride?

Any other better suggestions as to either attaching the GPS or cleanly installing the 12v socket?

Thank you in advance for any insight!

Geezer, I have been thinking along those same lines.  I have a garmin, but the concept is the same.  I do not think mine would stick to the curved windshield and I would be afraid to try.  If it falls off in the truck that is too bad, if it falls off of the bike it is gone.

I am thinking about some kind of tank bag, magnet mount thing under the speedometer.  This is in the early thinking stage.  I also thought about fixing a power outlet and putting it in the tool box (I think someone else suggested this somewhere).  The garmin has an internal batter that would last long enough for me to use without power.  I have not got anything definite though.

Here's where I mounted my 12v accessory plug for my GPS:

Do you have the details on yor GPS holder. Looks good. I myself was considering drilling the windshield and using small bolts with  rubber washers to attach the GPS mount. I haven't come across any GPS mounts that look like they will attach to the stock handle bars easily.

Skid: The suction cup mount came with my Garmin. It has only come off 1x and because of it's size/configuration, it won't fall through between the the bottom of the windshield and the tree, handlebars etc. I just reattached it at the next stop light. I have 1500 miles on this setup and move it between my cage and the bike as needed. Now I only spent $120 on my Garmin 205, but as you can see I added the rubber protector (from Walmart), and a $10 2-year replacement warranty. Still ALOT cheaper than the $500-$700 dollar special motorcycle GPS units offered. Great touch sensitive screen and was awesome navigating The Tail of the Dragon last weekend!

Come on guys. If you read the options for the Garmin in the "please spend more money" section of their info sheet in the box they mention a handle bar mount for motorcycles. I'm sure the other companys have the same. Suction cups seem never to work on curved surfaces anyway. Then when you add our thumpity little engine that can . . .

I did the 12 volt socket with two 16" or so pigtail wires from a department store wire tied to the frame under the right side of the seat. It's been there two years and can be rotated around the frame just enough to make it handy for whatever gets plugged into it. I used it mainly for jump starting before I got the new battery. I'm sure the leads are long enough to go under the tank and let you put it somewhere unobtrusive up front. Of course the 12 volt cord with my Garmin 205 is long enough to reach my sissy bar from the front of the bike so all I need is a passenger to hold it and tap me when it's time to turn.

Just found this site. Looks like it would work, but its gonna be close to $100 usd.

I tried my Garmin GPS suction mounted to the windshield.  I realize there is alot of difference between it sitting in the shed, nice and still and thumping and bumping along the road.  I put the GPS on yesterday morning and this morning it had fallen off, never having moved.  That was what I suspected would happen.  If yours stays stuck on, great but mine didn't.  I've never had a problem in the truck with it.  I am still going to think about this.
